Stimuli from Murray (2020)

This module reproduces most of the stimuli used by Murray (2020) as they were provided to the model described in that paper but normalized between 0 and 1. The stimuli are show in Fig 1 of the paper. NOTE that the Haze illusion (Fig 1m) is not provided.

Each stimulus is provided by a separate function, which can be listed using

>>> import stimupy.papers.murray2020
>>> help(stimupy.papers.murray2020)

The output of each of these functions is a stimulus dictionary.

For a visual representation of all the stimuli and their mask, simply run this module from the shell

$ python -m stimuli.papers.murray2020

or from within python

>>> from stimupy.utils import plot_stimuli
>>> from stimupy.papers import murray2020
>>> plot_stimuli(murray2020.gen_all())
